Application filed December 26, 1912. Serial No. 738,524.

To all whom it may concern Be it known that I, ALBERT T. ZAnmsKni, a citizen of the United States, residing at Passaic, in the county of Passaic and State 5 of New Jersey, have invented certain new and useful Improvements in Automatic Calendars, of which the following, taken in connection with the accompanying sheet of drawings, is a complete and ponci'se description.

The present invention relates to certain new and useful improvements in calendars, and has for its primary object to provide a mechanical calendar which embodies novel features of construction whereby it can be readily set for any month of any year within a ten thousand year limit.

The object of the invention is to provide a calendar of this character which is simple and inexpensive in its construction, which can be easily and quickly set for the desired month of the particular year, and which does not require 'anyjarithmetical or mental calculations on the'p'art of the operator.

to provide a gneehanical' calendar which is compact in its construction and can be very inexpensively manufactured so as to be susceptible of use for advertising purposes.

With these and other objects-in view, the invention consists in certain combinations and arrangements of the parts as will more roceeds,

the novelfeatures thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following def scription and accompanying drawings, in

which I Figure l is a la'n View of the calendar, showing the sa as set for the month of January 1912. Fig. 2 is a plan view of the calendar with the face thereof removed. Fig. 3 is a sectional view on the line 3-3 of Fig. 1. Fig. 4 is a plan view showing the calendar as set for the month of December 1912, and Fig. 5' is a rear view showing the table to which reference is made when setting the calendar. 7

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Specifically describingthe present embodi- 3 ment of the invention, the numeral 1 designates the face of the calendar; the said face A still further object of the invention is.

being formed with the sight openings 2 and 3 and being adapted to have any suitable advertising matter placed thereon. The sight opening'3 is arranged innnediatcly under the sight opening 2, with a strip {l interposed between the two sightopenings. The month slide 6 is mounted under the sight opening 2, whilethe key slide 7 is mounted under the sight opening 3.

Any suitable means may be provided for mounting the slides 6 and 7 back of the calendar face 1, and in the present, instance they are shown as arranged in slotted portions, 8 of an intermediate thickness of material 9 which is interposed between the face 1 and a backing 10. Each of the slides 6 and 7 is provided with an eyelet or finger piece 11 by means of which the slide can be moved back and forth within the guideway provided for the same for the purpose of setting the calendar.

The portion of the calendar face'l immediately above the upper edge of the sight opening '2 is subdivided into seven spaces having the days of the week printed or indicated therein, as indicated at 12, in the usual manner. The strip 4 between the two sight openings 2 and 3 is subdivided into seven;

vertical columns which are arranged directly under/the before mentioned spaces having the days of the week printed therein. In the first column appears the word. May, .in the second column appears the word Aug, in the third column appears the words Feb, Mar. and Nov., in the fourth column appears the word June, in the fifth column appear the words Sept. and Dec., in the sixth column apear the words Apr. and July, in the seventh appear the words Oct. and Jan. These words indicate the twelve months of the year, and under each of the words is the numeral designating the number of days in the month. Under the word Feb. arc the two numerals 28 and 29 L, indicating that.

February usually has 28 days although on leap year it has 29 days.

The month slide 6 which is movable under the vicw opening 2, is shown as subdivided by the lines 13 into thirteen vertical columns, exactly seven of the vertical columns being visible through the sight opening 2 at the same time and the said columns corresponding in width to the spaces over the top of th'e'sight opening in which the days of' the week appear. There are six horizontal rows of figures upon the month slide 6, the

said figures being adapted to designate the day of the month in the usual manner. In the upper horizontal column the first eight 'spaces are blank while the last five spaces contain the numerals l to 5 inclusive. .ln the second horizontal column, the first space is blank, the rcn'iaining spaces being provided with the numerals 1 to 12 inclusive. The third horizontal, column is provided with the numerals 7 to 19 inclusive, the fourth horizontal column is provided with the numerals 14 to 26 inclusive, the fifth horizontal column is provided with the numorals 21 to 31 inclusive, the last two spaces being blank. The sixth horizontal column is provided with the numerals 28 to 31 inclusive, the last nine spaces being blank. It will be observed that following down the various vertical columns of figures, the numorals increase by sevens in the same manner which is customary upon calendars, and regardless of the position to which the slide ('3 may be moved, the characters thereon will read continuously from 1 to 31 when. following out the successive horizontal columns in the usual manner employed in connection with calendars. 1n the present instance the finger piece 11 of the month slide 8 is ranged at the bottom of the seventh vertica. column.

The key slide 7 is shown as divided into thirteen spaces corresponding to the vertical columns of the month slide 6, the said spaces being provided with the key letters which, reading from left to right, have the followingordcr:--E, F, G, A, B, C, D, E, F, G, A. B, G. The finger piece 11 of this key slide is arranged at the bottom of the seventh space or subdivision.

In setting the calendar, a key or table is employed, such as is shown by Fig. 5. s table is provided withthe columns .1 in which appear the numerals from O 0 to 99 inclusive, the said numerals indicating the various years of each century. It Will be ob served that the numeral corresponding to every fourth or leap year appears twice, the letter T. appearing opposite one of the occurrences. The year columns 15 and century columns 16 are "arranged at the'side of the columns 14. and contain key letters corresponding to the letters upon the key slide 7. I

l'n order to set the calendar it is first necessary to refer to the table and run down the column 14: until the numeral therein is reached which corresponds to the year of the century. For the year 1912 the required numeral would he the numeral 12, since this is the twelfth year of the particular century. This also happens to be leap year so that we find both the numeral 12 and the numeral 12 L, the character B appearing in the column 15 after the numeral 12 L, while the character A appears in the year column 15 novaeoo alter the numeral 12. In the case of a leap year, the lcey letter B which appears oppo site the mimeral 12 1) would be employed for.

down the column 14 until he came to the numoral 19, the said numeral being the first halt oi the date 1912 and indicating the number of centuries which have already lapsed. In the century column 16 opposite this numeral 19'. the key letter B will be "found and the month slide 6 will be moved to bring the linger piece 11. thereof over the key letter l3 wherever it may appear upon the key slide 7. The calendar will then be properly set For the month of January in the year 1912. This position of the various parts is shown. by Fig. 1. y

In order to set the calendar for December 1912, the operator runs down the column 14 to the numeralv 12, and finds the key letter A in the year column 15 opposite this numeral. Although this .is ,a leap year it will be remembered that the key letter for the leap year is only employed in connection with the months of January and February. The key slide .7 is now moved to bring the character Athereou under the December column of the strip 4. By again running down the column 1 1 to the numeral 19, the

said. numeral indicating the number of cen turies which have already lapsed and cone spending to the first part of the date 1912,.

we find the key letter B in the century column 16 opposite the numeral 19. The month slide 6 1S now moved to bring the finger set the calendar, the key slide 7 is first moved to bring the correct key letter thereof, previously ascertained by reference to the table, under the correct month column of the strip 1., the month slide (3 being next moved to bring the finger piece 11 thereof directly over the correct key letter of the key slide 7, the said key letter being also ascertained by reference to thetable. In this manner the calendar can be quickly set for any desired month and it can be quickly ascertained upon what week day any particular date in the past or future either has fallen or will fall. Y

a tabular arrangement of By reference to the'bottom of the table it will be seen that from 1700 to September 2, 17 52, the century key would be the letter C, while from September 14, 1752 to 1799, the century key would be the letter F. 7
